Large group of red\orange objects moving across the night sky.This incident occurred between 8:35 and 9:00 PM on Sunday Jan 11th 2015. I was out walking my dog when I saw a group of red-orange lights in the southwest sky. There were 8 lights in the initial group moving southwest to northeast - a smaller group of 3 lights was following. The larger group started in a roughly triangular formation before re-forming into a more linear alignment - the smaller group was in a linear formation from the outset.After the larger initial groups had moved on there were 3-4 individual lights moving in the same direction. All of the lights were moving quickly but I have no idea as to speed. The objects made no sudden maneuvers or turns - but they appeared to be flying a defined course.There was some air traffic in the area (we are close to PHL approach) and the objects did not seem to be any higher than the 2 aircraft I saw that were on approach to PHL, so maybe 1000’ in altitude.The objects traveled for about 30-45 seconds in a northeasterly direction before disappearing. There was some patchy cloud cover but the objects were not obscured by the clouds, they just vanished.The objects flickered reddish-orange, no other lights\color were observable. There was no sound from any of the objects. The objects appeared to be bow-tied in shape, a dark center with the red-orange lights fanning out fore and aft.I was at the following lat/long when I made this observation - 39°56'07.2"N 75°18'15.9"W Reporter - 53 year old male, IT professional, I saw the entire event.Secondary observer (my brother) - 48 year old male, construction worker. He only saw the follow-up, single light events
